Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine tunnel excavation equipment, and in particular relates to a temporary supporting device for an anchor digger. Background Art

[0002] The geological conditions of coal mines in various parts of my country vary greatly, and the development of tunneling technology is extremely unbalanced. The mechanization, automation, and integration of tunneling are low, and there are many people, many accidents, and a poor environment. At present, the tunneling equipment such as cantilever tunneling machines used in large quantities in coal mines are not equipped with anchor protection devices. During operation, an anchor drilling vehicle needs to be added to the rear or the tunnel roof and side walls need to be anchored by manual anchoring, which increases the scope of construction operations and requires additional construction team members. The work efficiency is low and the labor intensity is high. In recent years, some equipment manufacturers have developed tunneling equipment with support functions in response to the needs of different coal mines for tunneling equipment. However, the existing forward-flipping single-column temporary support devices are mostly first-level or second-level telescopic systems. The main disadvantage is that the maximum support range is reduced when meeting the support of low spaces, and the front telescopic beam is suspended at a large distance from the roof, which cannot fully protect the safety of construction workers. Utility Model Content

[0006] Furthermore, the main beam transverse tube of the main beam is sleeved on the inner side of the front telescopic beam transverse tube of the front telescopic beam; the side telescopic beam longitudinal tube of the side telescopic beam is sleeved on the inner side of the front telescopic beam longitudinal tube of the front telescopic beam;

[0008] Furthermore, the top ends of the secondary telescopic cylinder and the tertiary telescopic cylinder are both provided with limit blocks.

[0009] Furthermore, positioning plates are provided at the ends of the primary telescopic cylinder and the secondary telescopic cylinder, and the positioning plates cooperate with the limiting blocks to achieve limiting.

[0010] Furthermore, a stopper is provided at the top end of the first-stage telescopic cylinder.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the drawings required for the implementation are briefly introduced below. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0024] It should be pointed out that the front end, front side and front part mentioned in the following embodiment are all the forward direction of the drilling, anchoring and protecting machine, and the rear is relative to the forward direction. Similarly, up, down, left and right are all referred to the forward direction of the drilling, anchoring and protecting machine, which will not be repeated below.

[0025] Embodiment: A temporary support device for anchor mining machine, the structure of which is as follows Figure 1 and Figure 2 As shown, it includes a side telescopic beam 1, a front telescopic beam 2, a main beam 3, an auxiliary telescopic beam 4, a cylinder swing seat 5, a left and right leveling cylinder 6, a front and rear tilting cylinder 7, a tilting cylinder support seat 8, a fixed cylinder support seat 9, a fixed cylinder 10, a lifting cylinder 11, a three-stage telescopic cylinder 12, a limit block 13, a two-stage telescopic cylinder 14, a first-stage telescopic cylinder 15, a front and rear leveling cylinder 16, a front and rear telescopic cylinder 17 and a side telescopic cylinder 18.

[0026] The temporary support device is located on the cutting part of the anchor digger. In the excavation mode, the temporary support is placed flat on the upper part of the cutting part, does not occupy the tunnel space, and does not affect the excavation work of the cutting part.

[0027] Reference Figure 3As shown, the main beam 3 increases the supporting area by the side telescopic beam 1, the front telescopic beam 2 and the auxiliary telescopic beam 4; specifically, the main beam cross tube 3.1 of the main beam 3 is sleeved on the inner side of the front telescopic beam cross tube 2.1 of the front telescopic beam 2; the side telescopic beam longitudinal tube 1.1 of the side telescopic beam 1 is sleeved on the inner side of the front telescopic beam longitudinal tube 2.2 of the front telescopic beam 2; the auxiliary telescopic beam longitudinal tube 4.1 of the auxiliary telescopic beam 4 is sleeved on the inner side of the main beam longitudinal tube 3.2 of the main beam 3, and the auxiliary telescopic beam cross tube 4.2 of the auxiliary telescopic beam 4 is sleeved on the inner side of the side telescopic beam cross tube 1.2 of the side telescopic beam 1.

[0028] The cylinder ends of a plurality of front and rear telescopic oil cylinders 17 are hinged on the inner wall of the main beam 3, and the piston rod ends of the front and rear telescopic oil cylinders 17 extend into the front telescopic beam 2 and are hinged to the inner wall thereof, thereby driving the front telescopic beam 2 to telescope forward and backward on the main beam 3 through the piston rods of the front and rear telescopic oil cylinders 17;

[0029] The cylinder ends of several side telescopic cylinders 18 are hinged on the inner wall of the front telescopic beam 2, and the piston rod ends of the side telescopic cylinders 18 extend into the side telescopic beam 1 and are hinged to its inner wall, thereby driving the side telescopic beam 1 to telescope and slide, and the auxiliary telescopic beam 4 is led by the side telescopic beam 1 to telescope left and right, thereby increasing the support area and ensuring the safety of the anchor drilling work.

[0030] Reference Figure 2 As shown, the main beam 3 is connected to the left and right leveling cylinders 6 with bolts, and the angle between the main beam 3 and the top plate is adjusted by the left and right swing of the left and right leveling cylinders 6 so that it is completely fitted with the top plate. The cylinder swing seat 5 is respectively connected to the left and right leveling cylinders 6 and the front and rear leveling cylinders 16 with bolts. The front and rear leveling cylinders 16 are fixedly installed on the first-level telescopic cylinder 15. The front and rear leveling cylinders 16 can adjust the angle so that the support beam and the top plate have the same front and rear angle and fit the top plate. The use of double swing cylinders further reduces the distance between the first-level telescopic cylinder 15 and the top plate, thereby reducing the minimum height required for the support to flip;

[0031] Reference Figure 4 As shown, the primary telescopic cylinder 15 is inserted into the inner side of the secondary telescopic cylinder 14, the boss 13.1 of the limit block 13 is inserted into the inner side through the side hole of the secondary telescopic cylinder 14, the limit block 13 is installed on the secondary telescopic cylinder 14 with bolts, and the secondary telescopic cylinder 14 is assembled with the tertiary telescopic cylinder 12 and the limit block 13 in the same way.

[0032] The three-stage telescopic cylinder 12 is inserted into the inner side of the fixed cylinder 10, and the fixed cylinder 10 is hingedly connected to the fixed cylinder support seat 9, and the fixed cylinder support seat 9 is arranged on the cutting part of the anchor mining machine; the cylinder body end of the front and rear tilting cylinder 7 is fixed on the tilting cylinder support seat 8; the piston rod end of the front and rear tilting cylinder 7 is connected to the fixed cylinder 10; the tilting cylinder support seat 8 is fixed on the anchor mining machine.

[0033] The lifting cylinder 11 is connected with the fixed cylinder 10, the third-stage telescopic cylinder 12 and the first-stage telescopic cylinder 15 through a pin shaft. The extension and retraction of the cylinder rod of the lifting cylinder 11 drives the third-stage telescopic cylinder 12 and the first-stage telescopic cylinder 15 to extend and retract. The second-stage telescopic cylinder 14 is a passive telescopic cylinder. A positioning plate 15.1 is welded on the outside of the first-stage telescopic cylinder 15. During the extension process, the positioning plate 15.1 contacts the limit block 13 to drive the second-stage telescopic cylinder 14 to extend. Since there is no sequence for the extension and retraction of the cylinder rod of the lifting cylinder 11, the second-stage telescopic cylinder 14 is prevented from being separated from the first-stage telescopic cylinder 15, and the second-stage telescopic cylinder 14 is limited by the same principle.

[0034] Reference Figure 5 As shown, when the lifting cylinder 11 is retracted, the secondary telescopic cylinder 14 is retracted on the tertiary telescopic cylinder 12 under the action of gravity and the stopper 15.2 of the primary telescopic cylinder 15.
